rx framing error<br />

Cause<br />

Usually this error indicates a hardware problem.<br />

Action<br />

Check the Ethernet cabling and connectors to locate a problem.<br />

Technical Notes<br />

A framing error occurs when the Ethernet I/O driver receives a non-integral unit of<br />

octets, such as 63 bytes and then 3 bits. (Ethernet specifies the use of octets.) Framing<br />

errors are caused by corruption of the starting or ending frame delimiters. These can<br />

be corrupted by some violation of the encoding scheme.<br />

Framing errors are a subset of CRC errors, which are usually caused by anomalies on<br />

the physical media. An "alignment/framing error" is a type of CRC error where octet<br />

boundaries do not line up.<br />
